Which of the following statements about the head of a chlorophyll molecule is incorrect?
Correct answer: D. It is hydrophobic
- A. It is a porphyrin ring or tetrapyrrole ring structure
- B. It is flat, square and light absorbing
- C. Composed of carbon and nitrogen atoms with magnesium as central metal ion.
- D. It is hydrophobic
Explanation
Chlorophyll molecules have a complex structure consisting of the hydrophobic tail region and hydrophilic head region because it needs to interact with the surrounding aqueous environment. Now this is the wrong option and the question did ask for an incorrect one, hence option d is right as it fulfills the criteria of the question.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
